Another common problem is caused by donkey shoes left on for too long. A lot of the mountainous terrain is quite rocky so owners often prefer to shoe their animals to protect their hooves. They do that in the active months for work but unfortunately, they also leave the shoes on throughout winter. Damp seeps in between the shoe and the hoof and causes the occurrence of thrush infection on the soft tissue of the hoof. There is no mistaking it, if only for the strong and foul smell.
